American education tends to concentrate on American history of slavery, so many American are ignorant about just how widespread slavery was/is in the Islamic world and how many Muslims until today consider it a regular institution explicitly endorsed by God.

I certainly wouldn't like to be a black manual worker in any Arab country. Even if you aren't a formally legally enslaved person, you will be treated as one.

Or any other place from Asia, ie nepalis or philippinos are treated absolutely horribly in many rich middle east places. That culture, barring exceptional ethical individuals, has nothing in common with modern western values.
